Copy DataTable to Another DataTable with Specific Columns using c#.net

Previously in THIS post, showed how to ADD, UPDATE, DELETE in a DataTable using C#.

Now i will show how to copy data from one table to another table for specific columns only as for the requirement at some situations.

Code :

    protected void btnCopy_Click(object sender, EventArgs e)
    {
        try
        {
            DataTable newTable = dt.DefaultView.ToTable(false, "Name", "Sal");
            GridView2.DataSource = newTable;
            GridView2.DataBind();
        }
        catch (Exception ex)
        {
            string ErrMsg = ex.Message;
        }
    }

Here dt is source datatable.
